The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Plastipak Iberia (EU register number RECYC268), which uses the VACUNITE (EREMA basic and Polymetrix SSP V-leaN) technology. The input is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post-consumer PET containers, including no more than 5% PET from non-food consumer applications. The flakes are pre-decontaminated in a first ■■■■■ reactor at high temperature under vacuum, before being extruded, pelletised and crystallised. The crystallised pellets are then ■■■■■ and submitted to solid-state polycondensation (SSP) in two parallel ■■■■■ reactor lines at high temperature, under ■■■■■ and ■■■■■. Having examined the challenge test provided, the Panel concluded that step 2 (■■■■■ reactor) and steps 4 and 5 (■■■■■) are critical for determining the decontamination efficiency of the process. The operating parameters to control the performance are temperature, pressure and residence time for steps 2, 4 and 5, as well as gas velocity for steps 4 and 5. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process is not of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs, including drinking water, for long-term storage at room temperature, with or without hotfill. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.
欧洲食品安全局食品接触材料、酶和加工助剂专家委员会（CEP）评估了采用VACUNITE（艾雷玛基础型和波利玛科SSP V-leaN）技术的Plastipak Iberia回收工艺（欧盟注册号RECYC268）的安全性。其输入物是经过热碱洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，主要源自收集的消费后PET容器，其中非食品消费应用的PET含量不超过5%。这些薄片在第一个■■■■■反应器中于高温真空条件下进行预去污，然后进行挤出、造粒和结晶。结晶颗粒随后■■■■■，并在两条平行的■■■■■反应器生产线中于高温、■■■■■和■■■■■条件下进行固态缩聚（SSP）。在审查了所提供的挑战试验后，专家委员会得出结论，步骤2（■■■■■反应器）以及步骤4和5（■■■■■）对于确定该工艺的去污效率至关重要。控制性能的操作参数为步骤2、4和5的温度、压力和停留时间，以及步骤4和5的气体速度。结果表明，这种回收工艺能够确保潜在未知污染物向食品中的迁移水平低于保守模拟的0.1 μg/kg食品的迁移量。因此，专家委员会得出结论，当以高达100%的比例用于制造与所有类型食品（包括饮用水）接触的材料和制品，并在室温下长期储存（有无热灌装均可）时，该工艺获得的再生PET不存在安全问题。由这种再生PET制成的制品不打算用于微波炉和传统烤箱，本评估不涵盖此类用途。
